C-bear BB65 for Look ZED frames and cranks.
Look uses oversized 65mm(OD) bearings, thus BB65, for its 695 road frame.
The LOOK ZED concept : crankset
According to LOOK,
“• ULTRA LIGHT AND RIGID CRANKSET
The New LOOK ZED 2 crankset was developed to be as light and rigid as possible. The ZED 2 weighs only 320 grams (one piece integrated crank arms and spindle), which makes it the lightest crankset currently on the market, with the highest stiffness to weight ratio amongst the competition.
• MONOBLOC CONSTRUCTION
The LOOK ZED 2 crankset is constructed using LOOK MONOBLOC technology. The two crankarms, the spider, and the bottom bracket spindle is one piece, molded at a very high pressure (VHPC). The proprietary lay up for the one piece crank is optimized for solid cohesion. The crankarms of the ZED 2 crankset are hollow with no aluminum inserts to weigh it down. The bottom bracket spindle has a custom form that allows it to pass through the bottom bracket for fast and easy installation and removal.”
